DEVlCE FOR TRANSMITTING MOTION SPECIFICATION forming part of Letters Patent No. 739,641, dated September 22, 1903. Application tiled June 26, 1992. Serial No. 113,230. (No model.)

To @ZZ whom, t 1v1/ty concern:

Be it known 'that I, GEORG Gor'rwALD BEITZEL, manufacturer, of No. 23 Norrebrogade, Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in Devices for Transmitting Motion and Specially Adaptable for Sewing- Machines, of which the following is a specification.

The subject-matter of my present invention is in some respects an improvement over that of a former patent of the United States issued to Ine-to wit, Patent No. 699,067-for transmitting motion. The device covered by the patent mentioned is essentially adaptable for use in sewing-machines. ism arranged as described in the patent the distance between the table-slab of the rna chine and the lowermost point of the mechanism is greater than is desirable and the drivin 0'shaft is too far from the table-slab of the machine. In consequence of these facts diiculties arise tending to interfere with perfect action when it is desired to actuate the carrier directly from an eccentricdisk mounted upon the driving-shaft. To remedy these diiiculties is a purpose of my present device.

The invention is illustrated on the accompanying drawings, in whichn Figures 1 and 2 show the device seen lin side elevation and in two diiferent positions,

Y xed plate e.

some of the parts being shown in section.`

Fig. 3 is the same seen in front elevation and in a third position, and lFig. 4 is a fragmentary elevation showing the pitman fr and its immediate connections.

a is the drivin g-shaft, mounted horizontally below the table-slab of the machine. c is the catcher, which is Vmounted upon a vertical axle d, capable of turning in a bearing in a The axle d is provided below the plate e with a disk f, and from the plate e are projecting downward two bearing-plates The'extremities of the bearing-platesg are provided with pivots h, on which a tube lo, by means of two pins t', constituting a rocking journal, can move in the vertical plane. Inside the tube 75 is located a revoluble axle m, passing through the tube k and firmly connected in front with an arm n, and at the back the axle m is provided with ahead o, resting against the rear end of the tube k.

With the mechan- The head o is provided with pins p, projecting into bearings q of a forked pitman r, the other end of which is tnrnably connected with a spherical pin s, mounted eccentrically upon a disk t on the shaft ct. The fork r is consequently able to turn freely in all directions on the pin s and is, in order to be mounted upon this pin, divided into two halves. The upper extremity of the arm n is made hollow for the purpose of receiving a pin u, which is mounted either directly upon the disk for upon a piece e, attached tothis disk. The axis of the pin u coincides with the axis 'of the arm n, and this latter axis passes through the point of intersection between the axis of the pins t' and that of the axle m.

When the shaft a is turned, the tube 7c is, by means of the forkr, moved up and down in the vertical plane aroundthe axis of the pins i. At the same time the axle m is turned forward and backward around its own axis, and the axle m being placed in the tube la it will also partake of the movement of this one. The arm n will therefore describe a conical surface with the point of intersection of the axis ofthe pins t and the axle m as vertex. The rotating movement of the shaft a will thus be transmitted as a rotating movement to the axle d.

The carrier w is, as shown on the drawings, mounted draggingimmediately upon the disk t, which is shaped in a suitable way and can alternately be raised or lowered by means of the disk.

It will be observed that the point of intersection of the center lines of the axles m 'L' forms the vertex for the conical surface described by the center line of the pin u when the catcher c is revolving.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A device for transmitting motion from one axle to another at right angles therewith, comprising a driving-shaft, a revoluble disk to be driven, a tube capable ot' a rocking movement, an axle disposed within said tube and free to move relatively thereto, said axle being connected with said driving-shaft, an arm mounted'rigidly upon said axle and projecting laterally from said tube,and a bearing ICO member connected with said arm and with said revoluble disk to be driven. f

2. A device for transmitting motion from one axle to another at right angles thereto, comprising a revoluble member, a movable arm connected therewith for operating the same and free to describe a conical surface, a rocking journal for supporting said arm, said arm being free to move relatively to said rocking journal, a longitudinal member connected rigidly to said arm and supported by said rocking journal, a pitinan connected with said longitudinal member, and a revoluble member connected with said pitman for actuatingr the same.

3. A device for transmitting motion from one, axle to another at right angles thereto, comprising a revoluble member, an arm counected therewith and free to describe a conical surface, a longitudinal member rigidly connected with said arm, and mounted to rock axially and to move in a vertical plane, a pitman connected by means of a pivotal joint to said longitudinal member, and a revoluble member connected with said pitman for actuating the same.

4. A device for transmitting motion from one axle to another at right angles thereto, comprising a revoluble member, an arm connected with said member, a shaft carrying said arm at one end, the said shaft being mounted to move radially in a predetermined plane and to rock upon its own axis, a pitman connected with the other end of the shaft and a revoluble member for actuating said pitman.

5. A device for transmittingv motion from one shaft to another at right angles therewith, comprising a driving-shaft, provided with a disk, a revoluble disk to be driven, a tube fulcrumed at one end, an axle located Within the tube and free to turn backward and forward therein around its own axis, a head on one end of the axle and resting against the corresponding end of the tube, a pitman connecting the said head of the axle with the disk on the driving-shaft, an arm rigidly'connected with the other end of said axle, and projecting laterally through said tube, and a pin connected with the disk to be driven and engaging a socket in the end of the said arm.

6. A device for transmitting motion from one axle to another at right angles therewith, comprising a driving-shaft, a revoluble disk to be driven, a tube capable of a rocking movement, an axle disposed longitudinally Within said tube and free to move relatively thereto, said axle being connected with said driving-shaft, and an arm fixed to said axle vand connected with said disk.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
